@ddstreet I've been looking into a different issue, which is due to the Netplan
renderer.
The renderer defaults to networkd on server/cloud and NetworkManager on
Desktop. Some apps expect NetworkManager, and break on systems configured with
networkd (e.g. UI network config, apt-daily, etc).

Hi Mathieu, I don't think Cosmic or Disco systemd are affected. They are
both >= v239, and Cosmic behaved fine when verifying

It would just be a shame having the LTS release remain broken with DHCP
configurations, that used to work before.

This means we'll need to identify what patches need to be applied on top

Is this crippling? Are we able to verify that dhcp customization work
despite anything missing in systemd? I think it's the case; but I'd like
a second opinion. To be clear: I think we can verify th
